Surfactant flow behaviour and the effect of cosolvent in the remediation of diesel oil in a contaminated alluvial aquifer

摘要: The reduction of hydraulic conductivity during the treatment hydrocarbon polluted soils by using surfactants may be an inconvenient factor for a good recovery pollutant. This study has shown that this permeability, which causes plugging porous matrix, can due neither to precipitation anionic in presence calcium ions nor clay minerals present small proportion medium. We point out phenomenon is essentially agglomeration micelles and show addition cosolvents like alcohols under specific conditions contributes improving both injectability surfactant solution efficiency treatment.
